Role of Cu + on ZnS:Cu p-type semiconductor films grown by sputtering: influence of substitutional Cu in the structural, optical and electronic properties
Résumé
ZnS:Cu films were synthetized by co-sputtering. A Cu content higher than 10.6 at% lead to changes as the shrinkage of the ZnS:Cu cell and development of a p-type behavior. These results are explained by the substitution of Zn +2 ions by Cu + ones.
